HiiT stands for "High Intensity Interval Training" and is hands-down one of the best ways to burn fat without causing your body to catabolize your own muscle tissue.

The HiiT workout DVD features three different high-intensity routines that are each 30 minutes or less, making these workouts perfect for you to use on days where you're short on time.

The first HiiT workout is 30/30, and as the title suggests, each interval is divided into 30 second high energy plyo reps, followed by an equal 30 second rest for a total of 16 tough intervals.

The second HiiT workout is 40/20 divided into 16 intervals. Each interval is divided into 40 seconds of high energy plyo reps, followed by a 20 second rest. Three additional one minute breaks are spread throughout the program.

The third HiiT workout is Double Wave Pyramid. In this workout are two rounds of intervals separated by only a one minute rest. In each round is a pyramid cycle of nine intervals, in which the first set starts with a 20 second interval, and works up to the top of the pyramid, increasing each interval by five seconds. The workout then works back down the pyramid decreasing each interval by five seconds.

Only a step is needed for the first two workouts. No equipment is needed for the third HiiT workout.

I downloaded the 40/20, for some reason each workout is a separate download, and it is intense. Yes, the intensity comes from within, but if you push hard, you'll be drenched in sweat. I'm in excellent shape but by the end, I was really looking forward to those 20 seconds of rest. I can't wait to get the other two! Excellent job!

Boy did Cathe kick my butt in this one. I've done high intensity and interval training for a while, but not with these kind of moves. What I love is that is the type of workout that will always keep you challenged because you can always go a little faster as you get more advanced. You can also try adding another height level to your step but be warned that it will fry your legs!

This is my first Cathe workout - and I am in love! I love the HIIT style cardios, and this workout really delivers. It is a go-to for me. I use it regularly with Tabatacise. I also love that you get three different workouts on one DVD. And, it's great that one of the workouts does not use any equipment - making it great for travel. This is a fabulous sweat fest that will burn tons of calories. Thank you Cathe for such phenomenal workouts!

My joints just cant take this type of workout. If you cant do high impact HIIT check out Cathes Low Impact series!

I love this cardio workout...It is short but really get my heart rate high!It is definitely effective. I did it twice by adding it to my fitness routine...did 30/30 yesterday before completing power hour.I felt my glutes more while performing my squat on power hour,.My top was soaked!This dvd is not for beginners even 30/30 is challenging, and tough...This is a must have in my opinion
